[Purpose]
Recruitment poster for a bicycle riding club, designed as a vertical A4-style sports flyer for local community signup, club bulletin boards, bike-shop display, and social media sharing.
Korean bicycle club recruitment poster with energetic hierarchy, realistic outdoor riding atmosphere, and practical event/signup information.

[Composition]
- Center hero zone takes about 55–58% of the frame vertically, with {히어로 이미지} as the main visual, showing real riding context such as road markings, riverside railings, mountain trail dust, helmets, water bottles, cycling jerseys, and sunlight on bike frames.
- Top header band occupies about 18% of the canvas, with {메인 헤드라인} set large and bold for instant recognition, supported by {서브 카피} as a smaller motivational line.
- Use {클럽명} and {종목} as the main club identifier near the top or upper-mid area, styled like a sports team badge, route label, or jersey patch.
- Lower information block is structured like an event poster, clearly presenting {정기 라이딩}, {모집 기간}, {집결 장소}, {참가비}, {가입 방법}, and {문의 연락처} in stacked cards or strips.
- Include a realistic sponsor/support area at the bottom with {스폰서 표기}, small partner-name slots, QR-style signup box, and ticket/membership-style information.
- Background should feel like a sporty outdoor poster: deep charcoal base with bright accent bars, speed-line overlays, route-map fragments, elevation graph motifs, tire-track texture, and {장식 그래픽}.
- Use an active edge-to-edge vertical rhythm with layered panels, diagonal energy, and readable information blocks suitable for both print and mobile viewing.

[3. CORE STRUCTURE]
1. Header area (top 18%): set {메인 헤드라인} in oversized bold Korean type, with {서브 카피} below it in a compact English/Korean supporting line style; add a small label such as “NEW CREW 2026” or “WEEKEND RIDE TEAM”.
2. Club identity block: place “클럽 {클럽명} · {종목}” under the headline or slightly overlapping the hero edge, using a compact badge, jersey-number tag, or route-sticker treatment for club recognition.
3. Hero image block (middle 55–58%): show {히어로 이미지} as the dominant visual with multiple riders, plausible bicycles, helmets, gloves, lights, hydration bottles, route signs, asphalt texture, greenery, and motion blur accents that make the recruitment poster feel lived-in and real.
4. Event information strip: present “정기 라이딩: {정기 라이딩}”, “모집 기간: {모집 기간}”, and “집결 장소: {집결 장소}” in a structured info band with icon-like separators, small route arrows, and distance/time chips.
5. Membership / ticket block: display “참가비: {참가비}” as a ticket-style tag or membership pass, with a small note area for first-ride guidance and safety gear reminders.
6. Signup block: display “가입 방법: {가입 방법}” and “문의: {문의 연락처}” in a strong callout area near the lower portion, including a QR-style square, Kakao open-chat style label, and clear call-to-action button.
7. Sponsor / footer area: add {스폰서 표기}, small partner logo placeholders, address-like microtext, page-safe footer details, and accent rules using {컬러 팔레트} so the poster feels like a real local cycling-club recruitment flyer.

[4. STYLE RULES]
- Typography: use Pretendard ExtraBold for the headline, Pretendard Bold for body details, and Noto Sans KR SemiBold for secondary labels; headline size should feel oversized like a sports campaign poster, with tight line spacing and strong weight contrast.
- Color palette: use {컬러 팔레트} with vivid red and yellow accents, charcoal black for the base, and green as a supportive highlight; include off-white text panels, colored stickers, and high-contrast badges where needed for readability.
- Layout detail: combine diagonal speed bars, map-grid overlays, elevation profile lines, small numbered info chips, route arrows, and tire-track textures so the poster contains realistic cycling culture cues.
- Border/shadow: use thin rectangular rules, bold section dividers, sticker-like outlines, and a soft drop shadow with 4px y-offset, 12px blur, 15% opacity for layered info cards.
- Text hierarchy: top headline must be readable first, club identity second, hero action third, and signup/event details fourth; keep all Korean information crisp and typographically consistent.

[5. VISUAL STYLE]
- Camera / lens: 24mm wide-angle sports poster look, as if shot on a Canon EOS R5 with RF 24mm f/1.8 at f/5.6 for deep scene clarity.
- Lighting: bright outdoor daylight with crisp directional sun from upper-left, mild rim light on helmets and bike frames, and controlled shadows for a high-energy action feel.
- Color grade: saturated sports-poster grade with strong red/yellow accents, deep charcoal contrast, natural green outdoor tones, realistic asphalt/forest texture, and punchy highlight separation.
- Rendering: realistic riders and bikes integrated with graphic poster overlays, not a plain studio composite; include convincing contact shadows, wheel perspective, jersey fabric texture, handlebar details, tire tread, and reflective helmet highlights.

[6. MOOD]
Energetic outdoor community recruitment poster with a bold Korean sports-club flyer rhythm, weekend adventure mood, friendly local-crew authenticity, and the excitement of joining a real group ride.

[7. CRITICAL]
- Korean text accuracy: must appear exactly as written for the poster content: “자전거 라이딩 클럽 모집”, “{메인 헤드라인}”, “{서브 카피}”, “클럽 {클럽명} · {종목}”.
- Event details must appear clearly: “정기 라이딩: {정기 라이딩}”, “모집 기간: {모집 기간}”, “집결 장소: {집결 장소}”, “참가비: {참가비}”.
- Signup and footer text must appear clearly: “가입 방법: {가입 방법}”, “문의: {문의 연락처}”, “협찬: {스폰서 표기}”.
- Maintain a vertical A4 recruitment-poster composition with one dominant hero image, clear hierarchy, realistic decorative cycling graphics, and readable information blocks.
- Keep all bicycle riders anatomically correct, bikes mechanically plausible, wheel geometry circular, helmets properly fitted, and group spacing consistent.
